2 Claims.

This invention has general reference to means or devices for removing and replacing articles out of normal manipulatory reach; and more particularly to means for inserting and removing the operative parts of emergency valves, for instance, into and from tank vehicles used for the transportation of inflammable and other liquids.

Specifically, the instant subject-matter is a division from prior application Serial No. 300,325, filed October 29, 1939, by the same applicant, and which matured as U. S. Patent No. 2,212,370, dated Aug. 20, 1940, while the primary object had in view is to furnish a remotely operable device for positive application or removal of the bonnet and associated operative parts, through the manhole, of vehicle tank emergency valves without any necessity of the operator entering such tank.

Another object is to provide a device of the indicated type which is simple and compact in construction, and easily actuable at a distance from an emergency valve, for example- Other objects, with ancillary advantages, achieved by this invention will be apparent from or are specifically referred to in the following detailed description of typical-embodiments of said invention, as illustrated in the accompanying sheets of drawings, while the features of novelty are more particularly expressed in the concluding claims.

In the drawings:

Fig. 1 is a fragmentary longitudinal section of one end of a truck tank showing the intended use of the inserting-removing device of this invention, in connection with an emergency valve.

Fig. 2 is a broken top plan view of the insertingremoving device.

Fig. 3 (sheet 2) is a fragmentary vertical section through the upper portion of the emergency valve with the inserting-removing device engaged therewith, said Fig. being drawn to a larger scale for the better illustration of otherwise concealed features.

Fig. 4 (sheet 3) is a View similar to the preceding but showing the valve bonnet and associated parts released and ready for lifting out of the tank, as eifected by the device of this invention.

Fig. 4 (sheet 2) is a fragmentary section, taken approximately as indicated by the arrows V-V in Fi 3.

T ig. 6 (sheet 2) is a perspective view of a hook or claw hereinafter particularly explained.

Fig. 7 is a sectional detail somewhat similar to Fig. 5, but showing a modified feature of this invention.

Fig. 8 is an exploded perspective view of the connected parts shown within the section confines of the preceding Fig; and,

Fig. 9 is a plan section, taken as indicated by the arrows IXIX in Fig. '7.

In all the views, corresponding parts are designated by like reference characters.

Referring more in detail to the drawings, and as set forth in the prior patent hereinbefore noted, the numeral l designates a broken end portion of a conventional vehicle tank, 2 the manhole, and 3 the emergency valve; said valve embodying an aperture upper housing 4 with an inner grove 5, for engagement by the tooth portion 0 of spring-influenced circumferentially-spaced 8 of the valve cover or bonnet 0. In the housing 4 is an upwardly-actuable lift-valve it, under the influence of a spring ll, while the stem l2 whereof extends upwards through the bonnet s and is fitted with a rigid bail l3, all of said parts being merely referred to by way of better explaining the inserting-removing device of this invention.

This device, comprehensively designated as M, comprises a length of tubing or body portion l5, having rigidly secured to one end a somewhat fork-like extension l6 with the wider extremities connected by a bridge II, in turn embodying a coupler projection [8, for attachment of an appropriate handle I9. Transversely of the fork-like extension I6 is journaled a reel 20, having a crank-handle 2i secured to one end of the axis pin or shaft 22, and whereby said reel is rotatable. Secured to the reel 20 is one end of a flexible or other suitable cable 23 which passes through the body tubing I5, and is trained over a freely rotative sheave 24, journaled on a clamp-bolt 25 having a wing nut 26, said bolt being passed through axially aligned holes 27, respectively in a forked attachment 28 at the other end of the tubular body portion l5, and similar holes 29 in the spaced ears 30 projecting angularly from a cap structure 3!, screw-threaded to one end of a tubular section 32. This section 32 is of an interior diameter for free passage over the valve cylindrical bonnet 9 on the valve covering flange 8, into seating engagement with the confronting face of an embossment 33 integral with said covering flange, as readily understandable from Figs. 3 and 4.

Firmly connected to the free end of the cable 23 is a suspension element 34 affording swivel support for an anchorage hook 35, through a bored portion 36 of which the cable 23 is passed before fixture of said element, whereas the clawportion 3! is appropriately shaped for easy passage through the valve stem bail l3.

In Figs. 7-9, inclusive, there is shown a modified form of anchorage device 38 for coupling the cable 23 to the valve bonnet 9, said device differing from that previously described in that the suspension element is more in the nature of a plumb 39, as clearly shown by the left-hand portion of Fig. 8 and it is provided with a part spherical top 4a; whereas the anchorage device 38 is inverted relative to the valve bonnet 9 and is secured to the valve stem l2. I'he device 38, it is also to be noted, is formed with a forked claw 4| merging inward to a slot 52 of a width to receive the cable 23, while the element top 43 coacts with a complemental rounding 43, provided for its stabilizing reception in the hook'lll.

In use of the inserting-removing device I4, it will be readily understood the operator grasps the handle I!) in one hand and releases or pays-out the cable 23 by turning the crank 2| to the left sufiiciently to lower the anchorage hook 35 below the free extremity of the tubular section 32, and after inserting the device l4 through the tank manhole 2, as shown in Fig. 1, manipulates said device until the hook claw 31 engages the valve stem bail l3; whereupon the crank-handle 2| is turned a few times to the right until the tubular section 32 telescopes over the valve bonnet 9' with its bottom in abutment agains, the embossment 33, as clearly shown in Figs. 3 and 4. Further rotation of the crank-handle 2| clockwise first pulls the valve ill above its normal lift or until the heels 44 of the latch devices I are engaged by the top face of said valve, and, rock such devices radially inwards of their respective pivots 45, and thereby release the tooth portions 6 from out of the groove 5, as best understood from Fig. 4. The crank-handle 2| may now be held in the just explained position, while the operator withdraws the device 14 and connected lift valve l3, out through the man-hole 2, for inspection or repair. To replace the lift valve ID, the operation above described will be, obviously, reversed. Attention may here be directed to the fact that by providing the clamp bolt 25 with. a wing-nut 2 5, the angular position of the tubular section 32 may be changed with respect to the body portion L5, in

order to accommodate easy manipulation when.

the valve 3 is otherwise locatedthan proximately below the man-hole 2, said section 32. and body portion I5 then being locked together by simply tightening-up the wing-nut 26.

amass While there has been described one specific usage of the removing-replacing or insertingremoving device I4, it will be clearly apparent the same is capable of other uses where any article having a bail, eye or the like may be grasped or picked up or set down, from a remote position, by a connecting and compressing tool.

From the foregoing it will be clearly understood that the invention disclosed fully justifles the objects set forth, and it is not desired to limit such disclosure to the exact details of construction shown and explained, for various modifications within the scope of the following claims may occur to those conversant with the art, hence it is intended to include all such changes, or other applications, of the inventive features herein as the state of the prior art permits.

Having thus described my invention, I claim:

1. A placing and removing device comprising a tubular body portion; an angularly adjustable tubular sect-ion at one end ofthe body portion; a fork-like element secured to the other end of the body portion and having the wider part spanned by a bridge; a handle projecting from the bridge; a reel journaled in the fork-like elemen-t; a rotarysheave freely mounted at the junction of the tubular body portion with the angularly adjustable tubular section; a flexible cable, having one extremity secured to the ,reel, passing through the tubular body portion over the rotary sheave and into the tubular section; and means at the free end' ofthe cable for anchorage with the article to be placed or removed, said means being also retractible into the tubular section to prevent its disconnection from the article during manipulation of the device.

2. A device for removing and replacing articles having a bail; said device comprising a tubular body portion having a handle at one end; an angularly adjustable tubular section pivotally connected to the otherend of the body portion; a freely rotatable sheave at the pivotal connected tubular portion and section; reeling means journaledto the handle end' of body portion; a flexible cable, having one extremitysecured to the reeling means, passed; through the body portion, over the sheave, and through the tubular section; and a swivel hook at the free end of the cable adapted for retraction within the tubular section.
